TIME? UTC and System Clocks...
Disclaimer: Non-pilot Librarian at aviation firm.
There seems to have been an analysis of the known and suspected tracks that was performed to determine if the plane was under human control inputs or solely under some mode of auto navigation during the initial period of "Somethings Gone Haywire" in hand off and unusual maneuvers phase.
I would question whether disparate systems of military radars would even be operating at the same system clock settings, particularly when it involves competing military officers.
Consider: System clock for an ATM transaction often differs by several minutes from System Clock for an ATM camera network. So a "noon" withdrawal from an ATM and a "noon" camera snapshot from that same ATM can be off by a few minutes. Also security system at major Miami hotel that displayed time frames on surveillance tapes of hallways, elevators and exit doors was found to be "off" by over fifteen minutes from actual event times.
Therefore, I would have doubts as to timing indications on disparate radar systems, particularly when primary returns are from different radar systems under different military jurisdictions. System clocks vary widely in all complex installations that are essentially a hodge podge of separately designed and separately installed systems.
